A bundled instruction file becomes active in detected third-party AI-agent environments. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.0.3 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm installation, the package detects third-party coding-agent installations and installs its bundled skill into their home-directory skill surfaces. This modifies Codex, Claude Code, Cursor, and similar agent control surfaces without an explicit user setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-15T22:54:15.095Z - **Finished:** 2026-08-15T22:55:04.088Z - **Download time:** 1016 ms - **Static scan time:** 2678 ms - **AI review time:** 45298 ms - **Total time:** 48993 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm installation, the package detects third-party coding-agent installations and installs its bundled skill into their home-directory skill surfaces. This modifies Codex, Claude Code, Cursor, and similar agent control surfaces without an explicit user setup command. - **Trigger:** npm postinstall - **Impact:** A bundled instruction file becomes active in detected third-party AI-agent environments. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/install-skills.mjs, skills/wan-cli/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-15T22:55:04.088Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic cross-agent skill deployment - **Attack narrative:** Installing the package runs postinstall, which calls installAgentSkills. That code detects coding-agent commands or applications and copies the bundled wan-cli skill into home-directory skill locations including .codex, .claude, and .cursor. This is an unconsented install-time mutation of foreign AI-agent control surfaces. - **Rationale:** The package has a concrete, automatic postinstall chain that writes a bundled skill into detected third-party agent directories. Under the firewall policy, this requires a publish block regardless of the otherwise package-aligned Wan CLI functionality. - **Files touched:** scripts/postinstall.mjs, scripts/install-skills.mjs, skills/wan-cli/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., postinstall invokes agent-skill installation without user confirmation., Installer detects installed coding agents and targets Codex, Claude Code, Cursor and others., Installer copies the bundled skill into detected agents' home-directory skill paths. - **Evidence against:** The bundled skill describes Wan video-generation workflows., Observed runtime API endpoints are Wan service endpoints; no postinstall network request or credential exfiltration was found. ## Public findings ### 1.
